<a name="id2549419"></a><h2>DESCRIPTION</h2>
<p>
<code class="function">lwres_net_ntop()</code> converts an IP address of
protocol family <em class="parameter"><code>af</code></em> — IPv4 or IPv6 —
at location <em class="parameter"><code>src</code></em> from network format to its
conventional representation as a string. For IPv4 addresses, that
string would be a dotted-decimal. An IPv6 address would be
represented in colon notation as described in RFC1884.
</p>
<p>
The generated string is copied to <em class="parameter"><code>dst</code></em> provided
<em class="parameter"><code>size</code></em> indicates it is long enough to store the
ASCII representation of the address.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id2549452"></a><h2>RETURN VALUES</h2>
<p>
If successful, the function returns <em class="parameter"><code>dst</code></em>:
a pointer to a string containing the presentation format of the
address. <code class="function">lwres_net_ntop()</code> returns
<span class="type">NULL</span> and sets the global variable
<code class="constant">errno</code> to <span class="errorcode">EAFNOSUPPORT</span> if
the protocol family given in <em class="parameter"><code>af</code></em> is not
supported.
